Which jungler should I play ?

As the title says, I am looking to expand my champ pool at the moment and wanted to know what you guys think, usually i just play the champ if I get the skin for him but now I don’t know which one I should try next. At the moment I main Shyvana and Nunu. Used to main Rammus, Amumu, Mundo, Eve and Wukong. (Have 2 skins for Lee-sin but afraid of the high skill ceiling). Also if you have some tips for Shyvana I would be very grateful.
